[Dsg-hallb_magnets] Can you give me an update on your check outs?

[Ruben Fair]

Thank you Pablo. 

We can review all the check sheets - as completed thus far, later today. I shall set up a meeting.

Hello Ruben, 

Here some updates on the Solenoid I&C. 

For the P010- Pre-Cooldown Valve Checkout Procedure: 
SV8675BY - was completed tested . 120 V AC and air supply line were connected this morning. No issues in controls and EPICS monitoring for the valve. 


Additionally, test for heaters on Lead A and Lead B. 
Tested heaters in a temperature range of 292 to 310 K. They reacted as expected. hardware wiring, PLC logic and EPICS indicators works properly. 
Values in the PLC code will be changed to keep a temperature range between 301 and 303 K. Same as Torus thresholds.That means at temp <301 K heaters will be turned on, and at temp >303 K heaters will be disable. 


Best Regards, 
Pablo

Many thanks Nick. 

I think for now, copy the relevant sheets from the previous P006 and attach to your current sheets. 

I hope to have the load cells connected later this morning 

Cheers 

Ruben
